lighting device

Abstract

The invention relates to an illuminating device which comprises a base. A fixed seat is arranged on one side of the base, a first bushing is arranged on the fixed seat, a hollow rod is slidably connected in the first bushing, a locking bolt is spirally connected to the first bushing, a lampholder is arranged at the top end of the hollow rod, a lamp is mounted at the bottom end of the lampholder, the lamp is covered by a lampshade, the lampshade is semi-spherical, and the top end of the lampshade is fixedly connected to the bottom end of the lampholder. According to the device, by forming two groups of threaded holes symmetrical to each other in the hollow rod, when the threaded holes in one side are loosened, the device can rotate and is fixed by the next threaded holes, so that the service life of the device is prolonged indirectly. An L-shaped rod and a spring in a compressed state all the way also help the hollow rod be fastened and fixed further. A supporting rod and a dovetail block sliding in a dovetail groove can fix the lampholder and the hollow rod and a slide bar slide more smoothly. A plurality of fixed plates help the device be fixed better.

Description

technical field [0001] The present invention relates to the technical field related to the invention, in particular to an illuminating device. Background technique [0002] With the development of science and technology and social economy, the progress of science and technology is affecting the social economy and changing people's way of life. Current lighting fixtures, especially outdoor lighting fixtures, are usually installed and fixed on outdoor walls or ceilings by using lamp poles, so that the lighting fixtures can be powered on and work in a safe, firm and stable environment, so as to realize stable lighting externally. Light illumination output. [0003] However, in order to facilitate the installation of existing lamp poles, the inner pole in the telescopic structure is changed into a hollow pole to reduce the weight of the structure, but at the same time, because the wall thickness of the hollow pole is relatively thin, it is difficult to use it for a long time. ...

Problems solved by technology

[0003] However, in order to facilitate the installation of existing lamp poles, the inner pole in the telescopic structure is changed into a hollow pole to reduce the weight of the structure, but at the same time, because the wall thickness of the hollow pole is relatively thin, it is difficult to use it for a long time. Finally, the connection between the locking bolt and the threaded hole used for fixing on the hollow rod is unstable, causing the entire telescopic structure to shake, causing inconvenient use of lighting fixtures and potential safety hazards, and because the whole is fixed on the wall through the base In this way, it may be caused by inadvertent collision, and torque will be generated at the connection between the telescopic structure and the base, resulting in unstable telescopic structure and potential safety hazards
